Nowadays,increasing amount of energy use and limited energy sources are important problem for all over the world. Because of this there is an increasing concern about new and renewable energy source researchs. Especially solar energy is a great alternative to petroleum-based energy sources and it is nearly limitless.In this study a monocoque body design and manufacturing of this body was examined. In design, the limited energy obtained from the solar panels to be used in the most efficient way, manufacturing of the vehicle is made as light as possible with a good aerodynamic shape for minimizing aerodynamic drag resistance. For this purpose the lower and upper shell of the vehicle has been manufactured from fiberglass. This body was used for NKU Gunesinoglu Solar Car team, at FORMULA G 2014 which is organized by TUBITAK.
